Abstract
A sensor element includes an analyte-permeable matrix which supports and maintains a sensing solution containing an analyte-sensitive indicator substance in a plurality of tiny vesicles. The sensor element is prepared by combining the sensing solution with an emuslifier that renders the solution dispersed within the matrix material. The sensing solution remains suspended in these dispersed vesicles after the matrix solidifies. A sensor element made in accordance with the present invention may be placed at the end of an optical fiber.
